Input data section in the controller

Without an input module, the valve system does not occupy any
data in the input section of the bus coupler, but does in the
diagnosis area.
Each input module occupies 1 byte in the input section of the
controller. If the address 0 (automatic addressing) is set, the VS
with inputs will act like a combination module.
The assignment of the input signals to the bit position can be
found in the following table. Here, byte 0 represents the first
byte (input module) in the process and is assigned to the first
input module to the left of the bus coupler.

Selecting the valve supply

With the S1, S2, S3, and S4 sliding switches (under the PG
fitting B), the valve power supply can be selected in blocks. It is
possible to switch between the valve supply from the DDL line
and the U and U
